5/13 Description The IF-D92 is a high-sensitivity NPN phototransistor detector housed in a “connectorless” style plastic fiber optic package. Optical response of the IF-D92 extends from 400 to 1100 nm, making it compatible with a wide range of visible and near-infrared LEDs and laser diode sources. This includes 650 nm visible red LEDs used for optimum transmission in PMMA plastic optic fiber. The detector package features an internal micro-lens and a precision-molded PBT housing to ensure efficient optical coupling with standard 1000 μm core plastic fiber cable. Application Highlights The IF-D92 is suitable for digital data links at rates up to 25 kbps. Analog bandwidths greater than 15 kHz are possible making the IF-D92 usable for high frequency audio transmission. Phototransistor operation provides high internal gain – reducing the amount of post-amplification required in many circuits. The integrated design of the IF-D92 makes it a simple, cost-effective solution in a variety of analog and digital applications.

Cross-section of fiber optic device. Fiber Termination Instructions 1.Cut off the ends of the optical fiber with a singleedge razor blade or sharp knife. Try to obtain a precise 90-degree angle (square). 2.Insert the fiber through the locking nut and into the connector until the core tip seats against the internal micro-lens. 3.Screw the connector locking nut down to a snug fit, locking the fiber in place. mA Figure 2.
